Abstract

Gallate material, a luminescent matrix with excellent performance is normally prepared by vapor deposition or solid phase sintering method at high temperature. However, it has not been solved to prepare gallate-based fluorescent materials with full-color luminescent properties at low temperature. In this paper, ZnGaO undoped or doped with Cr or Mn nanoflowers composed of nanosheet-level structure were prepared by hydrothermal method at low temperature. Under ultraviolet light irradiation, ZnGaO, ZnGaO:Mn and ZnGaO:Cr display three primary colors of blue, green and red luminescence through self-excitation, Mn and Cr excitation respectively. The solid fluorescence yields of blue, green, and red colors are 32.3, 36.5, and 40.7%, respectively. It is highly expected to be applied to color display, biological imaging, white light devices.

摘要

没食子酸盐材料是一种性能优异的发光基质，通常通过高温气相沉积或固相烧结法制备。然而，低温制备具有全色发光特性的没食子酸盐基荧光材料的问题尚未得到解决。本文采用水热法在低温下制备了由纳米片层结构组成的未掺杂或掺杂Cr或Mn的ZnGaO纳米花。在紫外光照射下，ZnGaO、ZnGaO:Mn和ZnGaO:Cr分别通过自激发、Mn激发和Cr激发呈现出蓝色、绿色和红色发光这三种原色。蓝色、绿色和红色的固体荧光产率分别为32.3%、36.5%和40.7%。其极具应用于彩色显示、生物成像、白光器件的潜力。
